Application filed January as, 19211 Serial no. 440,532.

One important object of the invention is to provide an improved form ofjar top which may be economically'manufactured and which may be appliedto a jar without the use of special machinery.

A second important obj ect' of the invention is to provide a novel andimproved form of such jar top or closure which will have improved meansfor holding the closure securely on a jar.

A third important object of the invention is to provide an improvedclosure having novel means for retaining a packing washer in properposition for application to a jar.

With the above and other objects in view, the inventlon consists ingeneral of certain novel details of construction and combinations ofparts hereinafter fully described, illustrated in the accompanyingdrawings and specifically claimed."

In the accompanying drawings like characters of reference indicate likeparts in the several. views, and 1- Figure 1 is a side elevation of ajar hav- 1 ing one form of the device applied thereto.

Figure 2 is a bottomplan view of a second form of the device.

Figure 3 is an enlarged detail section through an edge portion of theform shown in Figure 1.

Figure 1 is a side elevation, partly in section, of a jar having a topor closure of the.

form shown in Figure 2.

Figure 5 isa detail section through the edge of'the device before thebead is formed. Figure 6 is a modified form of the closure. In bothforms of the device there is provided a body portion 10 having adownwardly pressed center 11 concentric with and in spaced relation toits periphery. This downwardly pressed center 11 forms on the under sideof the top orclosure an annular flange 12. Depending inclinedly from theperiphery of the body portion of the closure is a flange 13 having atits lower edge in the form shown in Figures 1 and 3 an inwardlyprojecting beaded lip 14 arranged to engage beneath the lip 15 of a jar16.

In the form shown in Figures 2 and 4: the

bead of this lip is used to enclose a wire 19, the bead being open sothat the ends of the wire may be twisted together as at 20 to draw thelower edge of the flange inwardly and hold the flange lip securelybeneath the jar lip 15. v In each of the forms there is provided aseries of slits 21 cut entirely through the lip and extending upwardlyof the flange 13 to points adjacent the junction of said flange with thebody 10. and there terminating each in a substantially circular opening22 of slightly greater diameter than the width or the slit-so as toprevent all possible tearing.

at the upper ends of said slits.

Between the flange 12 and the flange 13 is fitted a packing washer orring 23 of some compressible material such as rubber or the like, thering being held from slip:

ping inwardly by said flange 12.

In applying this closure the jars are filled cold and the contentsheated. The top is then simply slipped on whereupon, as the contentscool, atmospheric pressure will force the closure down and hermeticallyseal the There has thus been provided a simple and eflicient device ofthe kind described and for the purpose specified.

Having thus described the invention, what is claimed as new, is

1'. ar top consisting of a central disk like body portion having adownwardly inclined peripheral flange when in operative positionspacedfrom the jar and provided at its lower edge with an inwardlyprojecting lip, said lip and flange being provided with a series ofspaced slits open at their ends through the lip, said slits eachterminating at'its upper :end in a substantially. circular opening-ofgreater diameter than the slit, said lip being beaded to provide achannel around the exterior of the flange, and a wire whereby to permitapplication of andre moval of the wire from the cap atwili.

2. A jar-top consisting of a central disk like body portion provided.with a down- Wardly proJecting flange concentric With'and in spacedrelation toits periphery and having adownwardly inclined peripheralflange when in operative position spaced from the jar and provided atits lower edge with an inwardly projecting lip, said lip and flangebeing providedwith 'a series/of spaced slits open at their ends'throughthe lip, said slits each terminating at its upper end in a substantiallycircular opening of greater, diamture.
